Between little, easy to assembly.
Embodiment 8
In embodiment 5-7, employ electromagnetic valve or reversal valve, it is therefore desirable to control described electromagnetic valve or four-way change-over valve
Electric-control system match therewith.Electric-control system can be integrated in air-conditioning master control, it is also possible to self-organizing system.
Embodiment 9
The one that the present embodiment is intended to illustrate to configure module heat-exchanger rig of the present utility model within air-conditioning systems is preferably
Embodiment, air conditioning system is heat pump type air conditioner.
In cooling mode, as it is shown in figure 1, through compressor discharge High Temperature High Pressure coolant through outdoor heat exchanger 1 cool down after
Becoming the liquid refrigerants of cryogenic high pressure, liquid refrigerants arrives at module heat-exchanger rig 5 after flowing through main refrigerant pipe 2 and the first check valve 3
Module is carried out cooling, then after throttle part 7 throttles, flows through the 3rd check valve 8 steam to indoor heat exchanger 10
Send out heat exchange.
Under heating mode, as in figure 2 it is shown, the High Temperature High Pressure coolant change after indoor heat exchanger 10 cools down discharged through compressor
Becoming the liquid refrigerants of cryogenic high pressure, liquid refrigerants flows through the second branch road 9 and the 4th check valve 6 arrives at module heat-exchanger rig 5 mould
Block dispels the heat, then flows through the second check valve 4 after throttle part 7 throttles and be evaporated heat exchange to indoor heat exchanger 1.
As can be seen here, air conditioning system of the present utility model, it is particularly suited in refrigerating and heating type air-conditioner, it is ensured that always use warp
The control device that liquid refrigerants is air-conditioning crossing cooling dispels the heat.
Embodiment 10
In the present embodiment, module heat-exchanger rig is arranged adjacent to the variable frequency drive unit of air conditioning system.Driving of convertible frequency air-conditioner
The heat that the work of dynamic model block produces is the highest, if be under scorching temperature weather conditions, radiating effect is poor, drives module long-term
Being under high temperature and work, reliability can be greatly affected.Coolant heat radiation is used effectively to lower the temperature for driving module；And this
Utility model adjusts coolant and flows to, it is ensured that in the case of the coolant that causes two kinds of mode of operations is in opposite direction, can utilize cold
Coolant before matchmaker's throttle part, to driving module cooling, solves driving near modules predictably and is likely to be due to cooling excessively
The problem resulting in condensation water.
Generally, this utility model uses different pipeline and the one-way conduction effect of check valve, makes air-conditioning in refrigeration, system
State when coolant flows through module heat dissipating under heat pattern is all the liquid refrigerants of cryogenic high pressure, and now refrigerant temperature is less than module temperature
Degree and the dew point temperature higher than air, not only can reduce the temperature of module, and the problem that turn avoid module condensation.
To sum up, skilled addressee readily understands that, on the premise of not conflicting, above-mentioned each advantageous manner can be certainly
By ground combination, superposition.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model,
All still fall within the range of technical solutions of the utility model.
